Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ ποιήσεις κατακάλυμμα τῇ σκηνῇ δέρματα κριῶν ἠρυθροδανωμένα καὶ ἐπικαλύμματα δέρματα ὑακίνθινα ἐπάνωθεν
Also make a covering for the tent out of ram skins dyed red, and over that a covering of fine leather (note: Possibly the hides of large aquatic mammals).
